摘要： A method and apparatus for determining the occurrence of a mis-location of an atrial electrode in a cardiac stimulation device having an atrial pulse generator coupled with the atrial electrode and a ventricular sense amplifier coupled to a ventricular electrode. The device paces the atrium in a first pacing mode employing atrial pacing pulses at a first energy level and in a test mode employs higher energy atrial pacing pulses. In the test mode the device measures PR intervals between atrial pacing pulses following sensed ventricular depolarizations and determines that the atrial electrode is mis-located responsive to occurrence of a threshold number of short PR intervals or that the atrial electrode is appropriately located responsive to occurrence of a threshold number of long PR intervals. Operation of the device in the test mode may be pre-conditioned on an absence of atrial tachyarrhythmia.

摘要： The invention relates to the use of atrial pacing therapies to treat atrial tachycardia (AT). When an AT episode is detected, an implantable medical device applies an ATP therapy. If the AT episode persists, the ATP therapy may be automatically reapplied at a later time during the course of the same AT episode. In particular, previously used ATP therapies are reapplied when episodic conditions, such as cycle length or cycle regularity, change. Although a particular ATP therapy initially may be unsuccessful in terminating the AT, it may prove successful when the cycle length or regularity of the atrial rhythm changes. As the rhythm slows down, the AT may be more responsive to ATP therapies that were previously unsuccessful. As a result, potentially efficacious ATP therapies can be reapplied to terminate AT episodes, and reduce the number of episodes that require more aggressive termination by painful, atrial shocks.

摘要： A device implemented software system for use with atrial and/or ventricular rate stabilization to adjust DDD/R rate stabilization while maintaining intrinsic ventricular response timing to overdrive the intrinsic sinus (atrial) rate. Specifically, the algorithm is directed toward maintaining ventricular activation/contraction sequence while improving atrial and ventricular hemodynamics. Generally, the PAV interval is prolonged subsequent to a sensed premature beat. In an ultimate embodiment, the algorithm enables extension of the PAV interval subsequent to a non-conducted premature atrial event. The extension of the PAV interval allows for the simultaneous smoothing of the atrial and ventricular rates.

摘要： A medical device selects the most appropriate among various calculated escape intervals for use in the next cardiac cycle. This is particularly implemented in cardiac event in which a pacemaker is used to prevent multiple tachyarrhythmias. The prevention pacing modes may be simultaneously active, with the escape interval for each mode calculated and updated on a beat-by-beat basis. The medical device selects tachyarrhythmia prevention pacing modality to control the escape interval of the current cardiac cycle in order that a more appropriate method for calculating the escape interval based on the present condition of the patient, may be selected.

摘要： An atrial and ventricular pacemaker including an atrial pulse generator having the capability of delivering high rate atrial pacing pulses for electrophysiologic study and having the capability of delivering ventricular pacing pulses as a backup, during delivery of high rate atrial pacing pulses. Delivery of backup ventricular pacing pulses may be preconditioned upon the occurrence of a desired number, proportion or pattern of occurrences of paced ventricular beats preceding delivery of high rate atrial pacing pulses. Timing of ventricular backup pulses is synchronized to delivered atrial pacing pulses which occur closely timed to expiration of a defined ventricular escape interval for backup pacing. The defined escape interval for ventricular backup pacing may be set as a function of the average interval separating ventricular events preceding initiation of high rate atrial pacing.

摘要： A rate-responsive cardiac pacemaker implements a novel pacing mode, identified as ADIR/VVIR, which is especially effective for patients with Sick Sinus Syndrome and only intermittent atrioventricular block. Within the same pacemaker circuitry, an AAIR pacemaker and a VVI pacemaker (with an escape rate below that of the AAIR pacemaker) are provided with atrial blanking following both atrial and ventricular events. Ventricular blanking after atrial pacing is minimized for better detection of R-waves following an atrial paced event.
